Spacermesh structure for shoemaking

ABSTRACT

A spacermesh structure is provided for shoemaking, wherein an intermediate intensive texture enclosed by an upper and a lower mesh-texture layer of a conventional typical sandwich structure is substituted by an intermediate layer having a plurality of supporting lumps woven thereon and aligned in one direction or in both the vertical and the horizontal directions staggeringly, and a plurality of reinforcement supporting girders is laid in some empty lanes in the intermediate layer for structure reinforcement, which, the girders, may be ropes, flexible bands, foam plastic strips, plastic strips, spring coils, metallic bars, etc.

FIELD OF THE INVENTION

[0001] This invention relates to a spacermesh structure for shoemaking,wherein an intermediate intensive texture enclosed by an upper and alower mesh-texture layer of a typical conventional sandwich structure issubstituted by an intermediate layer having a plurality of supportinglumps woven thereon and aligned in a single direction or in both thevertical and the horizontal directions staggeringly and a plurality ofreinforcement supporting girders is laid in some empty lanes in theintermediate layer for structure reinforcement, which, the girders, maybe ropes, flexible bands, foam plastic strips, plastic strips, springcoils, metallic bars, etc.

BACKGROUND OF THE INVENTION

[0002] The conventional spacermesh structure for shoemaking is usuallycomposed of an upper and a lower mesh-texture layer as well as anair-permeable and flexible intermediate intensive texture. Nevertheless,with more or less insufficient strength, poor plasticity and durability,and larger deformation, such a structure is thus compressed in itsapplicable field to some extent in despite of supplementary efforts.

[0003] In view of abovesaid imperfection, after years of constantefforts in research, the inventor of this invention has consequentlydeveloped an improved mechanism pertaining to the subject matter to bedescribed below.

SUMMARY OF THE INVENTION

[0004] The primary object of this invention is to provide a spacermeshstructure for shoemaking, wherein an intermediate intensive texture of aconventional typical sandwich structure is substituted by anintermediate layer having a plurality of supporting lumps woven thereonand aligned in one direction or in both the vertical and the horizontaldirections staggeringly and a plurality of reinforcement supportinggirders is laid in some empty lanes in the intermediate layer forstructure reinforcement, which, the girders, may be ropes, flexiblebands, foam plastic strips, plastic strips, spring coils, metallic bars,etc.

[0005] For more detailed information regarding advantages or features ofthis invention, at least an example of preferred embodiment will beelucidated below with reference to the annexed drawings.

BRIEF DESCRIPTION OF THE DRAWINGS

[0006] The related drawings in connection with the detailed descriptionof this invention, which is to be made later, are described briefly asfollows, in which:

[0007]FIG. 1 shows a conventional spacermesh structure for shoemaking;

[0008]FIG. 2 is an exploded view of the conventional spacermeshstructure;

[0009]FIG. 3 shows an embodiment of the conventional spacermeshstructure;

[0011]FIG. 5 is a schematic view of an embodiment of this invention.

DETAILED DESCRIPTION OF THE INVENTION

[0012] As illustrated in FIGS. 1 and 2, a conventional spacermeshstructure (1) for shoemaking usually comprises an upper mesh-texturelayer (11), an intermediate intensive texture layer (12), and a lowermesh-texture layer (13) to form a kind of soft shoe stuff with excellentair-permeability. However, a sandwich structure like this isparticularly insufficient in structural strength and weak in wrappingfitness that it would deform too much to keep itself in placeaccordingly.

[0013] For improvement, as indicated in FIG. 3, a relatively strongerplastic strip (15) or something the like is applied on the vamp forreinforcement, which, as a matter of fact, doesn't avail very much.

[0014] Now, referring to FIG. 4—a reinforced spacermesh structure ofthis invention, the framework (2) contains an upper mesh-texture layer(21), a lower mesh-texture layer (23), and an intermediate layer (22)having a reinforcement zone (24) with empty lanes to establish aspacermesh structure with excellent air-permeability and flexibility. Aplurality of supporting lumps is aligned in a single direction or twoperpendicular directions staggeringly in the intermediate layer (22),wherein a plurality of reinforcement supporting girders (25) is laid inthe empty lanes of the reinforcement zone (24); and the supportinggirders (25) may be ropes, flexible bands, foam plastic strips, etc.

[0015] In an embodiment of this invention shown in FIG. 5, thereinforced spacermesh structure (2) is applied for shoemaking in form ofa front segment (26), a middle segment (27), and a rear segment (28) ofvamp for consolidating the shoe structure and holding the vamp in dueplace.

[0016] In the above described, at least one preferred embodiment hasbeen described in detail with reference to the drawings annexed, and itis apparent that numerous variations or modifications may be madewithout departing from the true spirit and scope thereof, as set forthin the claims below.

What is claimed is:
 1. A spacermesh structure for shoemaking,comprising: an upper mesh-texture layer; a lower mesh-texture layer; andan intermediate layer having a plurality of supporting lumps woventhereon and aligned in one direction or in both the vertical and thehorizontal directions staggeringly, wherein a plurality of reinforcementsupporting girders is laid in reserved empty lanes in the intermediatelayer for structure reinforcement, which, the supporting girder, isrope, flexible band, foam plastic strip, plastic strip, spring coil, ormetallic bar.
